Answer:
0.3797 or 37.97%
Step-by-step explanation:
According to the scenario, computation of the given data are as follow:- 
Wants Rate on return on investment = 50% 
Expected value of return on investment = invested amount × (1+g)^t 
= $1,000,000 × (1+50%)^5 
= $1,000,000 × 7.59375 
= $7,593,750 
Similar venture would achieve valuation of $20,000,000 for $2,000,000. We can expect that company would achieve similar valuation of $20,000,000 in 5 years from now. 
Investor’s share value at 5 years = $7,593,750 ÷ $20,000,000 
= 0.3797 or 37.97%
